Abstract
The utility model discloses a storage tank buoyancy chamber steel plate with water-based nontoxic epoxy anticorrosive coatings, which is applied to anticorrosive construction in a closed space of an oil storage tank buoyancy chamber. The storage tank buoyancy chamber steel plate is characterized in that reserved welding sections are formed on the edges of the steel plate; the water-based nontoxic epoxy anticorrosive coatings are coated on the upper surface and the lower surface of the steel plate; the steel plate is 3m to 5m long, 0.8m to 1.5m wide and 3mm to 8mm thick; each reserved welding section is 100mm wide; and each water-based nontoxic epoxy anticorrosive coating is 0.08mm to 0.15mm wide. The storage tank buoyancy chamber steel plate has the effects of having properties of impact resistance, salt spray resistance and chemical medium resistance, and being capable of effectively prolonging the service life of the buoyancy chamber; and moreover, the steel plate has outstanding advantages in environment protection and security in anticorrosive construction in the closed space of the storage tank buoyancy chamber and the like, and can be applied to other anti-corrosion engineering with steel structures.
Description
Technical field
The utility model relates to petroleum storage tank and prepares the steel plate technical field, and particularly storage tank buoyancy module steel plate is the storage tank buoyancy module steel plate that a kind of two sides is sprayed with the aqueous non-toxic epoxy anticorrosive coating, is used for the anticorrosive construction of petroleum storage tank buoyancy module confined space.
Background technology
At present, the steel structures such as petroleum and petrochemical industry storage tank are strong because of corrosiveness of the environment of living in, performance requriements to used anticorrosive paint is higher, and along with the increasingly stringent of environmental demands, progressively forbids adding the antirust color stuffing that contains heavy metal and improve coating antiseptic erosion performance in coating.Existing preparation tank plate adopts aqueous epoxy coating to carry out anticorrosion with painting, has following point more: 1) adhesive ability, shock-resistant, salt spray resistance and chemical mediator-resitant property are relatively poor.2) antiseptic property is compared with solvent based coating larger gap, can not satisfy the requirement of the steel structure anti-corrosions such as petroleum and petrochemical industry storage tank; 3) the antirust color stuffing that contains heavy metal by interpolation improves the antiseptic property of coating, can not satisfy present environmental demands.
The utility model content
The purpose of this utility model is: a kind of storage tank buoyancy module steel plate that the aqueous non-toxic epoxy anticorrosive coating is arranged is provided, be adapted at the confined space anticorrosive constructions such as storage tank buoyancy module, do not contain heavy metal and inactive solvent, have good adhesive ability, shock-resistant, salt spray resistance and chemical mediator-resitant property.
The technical solution adopted in the utility model is: the storage tank buoyancy module steel plate that the aqueous non-toxic epoxy anticorrosive coating is arranged, comprise steel plate, at the steel plate edge reservation welding section is arranged, it is characterized in that: upper surface and lower surface at steel plate are coated with the aqueous non-toxic epoxy anticorrosive coating, steel plate long 3～5m, wide 0.8～1.5m, thick 3～8mm, the width of reserving welding section is 100mm, and the thickness of aqueous non-toxic epoxy anticorrosive coating is 0.08～0.15mm.The surface of reserving welding section does not spray the aqueous non-toxic epoxy anticorrosive coating.
The more excellent storage tank buoyancy module steel plate that the aqueous non-toxic epoxy anticorrosive coating is arranged is characterized in that steel plate length 3.5m, width 1m, thickness 5mm, and the width of reserving welding section is 100mm, and the thickness of aqueous non-toxic epoxy anticorrosive coating is 0.1mm.
Of the present utility model a kind ofly have the storage tank buoyancy module steel plate manufacturing process of aqueous non-toxic epoxy anticorrosive coating as follows: with upper surface and the lower surface sand blasting of steel plate, and spray the aqueous non-toxic corrosion-resistant epoxy paint at upper surface and the lower surface of steel plate except reserving welding section.Above-mentioned prefabricated steel plate is transported to the constructions such as weld at the scene, coating and becomes the storage tank buoyancy module.
The beneficial effects of the utility model: the utility model has the storage tank buoyancy module steel plate of aqueous non-toxic epoxy anticorrosive coating, do not contain heavy metal in the anticorrosive paint, have good adhesive ability, shock-resistant, salt spray resistance and chemical mediator-resitant property, especially resistance to acids is outstanding, anti-10% sulfuric acid soaked 30 days, coating is intact, and the life-span of buoyancy module is longer.Production technology is simple, cost performance is high, can be used for the confined space anticorrosive constructions such as storage tank buoyancy module, also can be used for the antiseptic project of other steel structures simultaneously.
Description of drawings
Fig. 1 is the cutaway view that the utility model has the storage tank buoyancy module steel plate of aqueous non-toxic epoxy anticorrosive coating.
Among the figure: the 1-steel plate; 2-reserves welding section; 3-aqueous non-toxic epoxy anticorrosive coating.
The specific embodiment
Embodiment 1:, the utility model is described in further detail as example take a storage tank buoyancy module steel plate that the aqueous non-toxic epoxy anticorrosive coating is arranged.
Consult Fig. 1.The utility model has the storage tank buoyancy module steel plate of aqueous non-toxic epoxy anticorrosive coating, comprises steel plate 1, steel plate 1 length 3.5m, width 1m, thickness 5mm.Along the welding section 2 of reservation is arranged, the width of reserving welding section 2 is 100mm in steel plate 1 surrounding.Upper surface and lower surface at steel plate 1 are coated with aqueous non-toxic epoxy anticorrosive coating 3, and the thickness of aqueous non-toxic epoxy anticorrosive coating 3 is 0.1mm.The surface of reserving welding section 2 does not spray aqueous non-toxic epoxy anticorrosive coating 3.
The material of aqueous non-toxic epoxy anticorrosive coating 3 is a kind ofly to have added the coating that ion-exchange type non-poisonous antirust pigment, calcium exchange silica gel and glass flake are made by aqueous epoxy curing agent, form coating in normal temperature cure, anti-10% sulfuric acid of this coating soaked 30 days, and coating is intact.
